BRICKOR TILE CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,192, dated July 13,1897. Application filed May 26, 1896. Renewed April 29, 1897- Serial No.684,461. (No model.)

To aZZ whom, it may concern:

Be'it known that we, JOHN O. LUDLAM and JOHN L. lVICKITTRICK, citizensof the United States, and residents of Canton, county of Stark, State ofOhio, have invented a new and useful Improvement in Brick or TileCutting Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

Our invention relates to an improvement in brick and tile cutters, theobject of which is to provide a cutter in which the cutting-wires willpass through the column of clay obliquely to cut downwardly and forward,thereby producing to a certain extent a draw out.

WVith this object in view our invention relates to certain features ofconstruction and combination of parts, as will be hereinafter describedand claimed.

Figure 1 of the accompanying drawings is a side elevation of a brick andtile cutter illustrating our invention. Fig. 2 is cross-section on line00 x on Fig. 1, showing the position of the parts when the cut ispartially made. Fig. 3 is a similar section showing the parts inposition after completing the cut. Fig. 4 is a perspective of a fragmentof parts slightly enlarged, showing detaili Fig. 5 is a similar view ofa worm and a segment of worm-wheel having a rotatable arm extension andpitman connection with the cutter-supporting frame.

A denotes the base, provided on its upper face with a suitable track orway on which the sugporting-w-he'elsB may travel.

denotes the longitudinally-vibratable frame.

D denotes a swinging frame having at its end portions a vertical arm E,the upper end portion of which is pivotally secured to the end portionsof the frame F. An arm, as G, projects rearwardly from the swingingframe D, which will be explained farther 011. About central to theswinging frame D is provided an outwardly-proj ectin g arm H, having atits outer end a journal-box a, adapted to the crank-pin J. The arm H isformed of two portions H and D, the former provided with an externalscrew-thread and the latter with an internal screwthread. The former isturned into the latter and secured in desired adjustment by thecheck-nut cl. By the lastnamed devices the arm H, which serves as apitman connection with the crank-pin J, may be lengthened or shortenedto give the proper vibration to the rocking frame which carries thecutting-wires and to move the cutter-supporting frame F on frame Otransverse the o1ay-supporting table L.

The rocking or vibratable frame is composed of the end frames K, whichare pivotally secured to the frame F by trunnions c, supported insockets f. The end frames K aresecured together by cross-bars L and L,on which the cutting-wires M may be secured in any of the well-known andapproved ways.

The cutting frame formed by the end pieces K and cross-bars L and L" isconnected to the frame D by the links N, pivotally connected I to thearm .G on frame D.

0 denotes a continuously-rotating shaft, having mounted thereon a wormP, that engages a segmental wheel Q, (see Fig. 5,) said wheel having anoutwardly-projected arm R, having at its outer end a wrist-pin h. Theside bar S of the horizontally-movable frame O is provided with astud-pin 7a. The pins h and 7c are connected by a pitman-rod T, by whichthe frame O, with frame F supported thereon, is moved from right to lefton the frame A, the worm-wheel having passed out of engagement with theworm, the arm R having passed below the supporting shaft or pin U, thecolumn of clay passing over the rollers m onto the table L will move thetable L and frame 0 to the opposite end of the stroke of the arm R,which has now completed a full revolution, at which instant the worm Pwill engage the cogs of wheel Q to rotate the arm the other half of thestroke or back to the place of. beginning. During this longitudinalmovement of frame C the frame F will be moved by the crank-pin J acrossthe supporting-frame C under the table L, carrying with it thecutter-actuating frame D and. the cutter-frame K. The rotary movement ofthe crank J and pin J will raise and depress the frame D, by which thecutter-frame will be rocked on its pivotal connection to the frame F tochange the angle of the cutting-wires. For instance, in Fig. 2 the partsare shown at the middle of the out, the crank down and moving in thedirection of the arrow, the top or upper end of the cutting-wire inadvance of the lower end to give the wire a downward and raking cut inthe column of clay, by which the cut on the top side of the brick willbe smooth. In Fig. 3 the parts show the cut completed and the frame Kbeing rocked or tipped to carry the top of the cutting-wire over to theopposite side and forward of the lower end, by which is produced areversed downward draw out.

Any suitable mechanism may be employed to reciprocate the frame orcarriage O, and in the present instance we have shown a set of wheels WVX Y Z, but these form no part of our present invention, and a fulldescription of the same is not deemed necessary.

Having thus fully described the nature and operation of our invention,what we claim is 1. The combination in a brick and tile cutting machine,of a reciprocating clay-table, a cutter-frame, and means forsimultaneously oscillating and transversely moving the cutter-frame inone direction through the uncut column of clay, and simultaneouslyoscillatin g and transversely moving the cutter'frame in the oppositedirection through the uncut column of clay, substantially as set forth.

2. The combination in a brick and tile cutting machine, of asupporting-frame, and reciprocating table, the movement of whichcoincides with the movement of the column of clay, a pivotedcutter-frame, and means for rocking it in opposite directions throughthe column of clay to make two distinct cuts therethrough, substantiallyas set forth.

the frame, F, and adapted to rock on its pivotal connections with theframe, F, and move transversely of the clay-table, substantially as setforth.

4:. The combination in a brick and tile cutting machine, of thelongitudinally-movable frame O,the actuating-shaft 0, having mountedthereon, a worm P, a segmental wormwheel Q, having an outwardly-projectin g arm R, and link T, whereby said arm is connected to frame 0,substantially as set forth.

5. The combination, in abrick and tile cut ting machine, of thelongitudinally-reciprocating supporting-frame, an actuating-shaftprovided with a gear, a mutilated gear meshing with the first-namedgear, and a link connecting the mutilated gear with thelongitudinally-reciprocating supporting-frame, substantially as setforth.

In testimony whereof we have hereunto set our hands this 19th day ofMay, A. D. 189 6.
